Weird FFB with the game?

New to this game and its hard to explain but my wheel, TX full fat, feels like its wavy around corners... it feels way way off and getting no useful feedback at all. Where am i going wrong? I'm on Pure 360, wheel rotation 540, ffb 100 and low 40.

help i really want to love this game.
GSCE and RRE and AC are all fine.
